Bank switching

Okay kiddo, so imagine you have a toy box with lots of compartments. Each compartment can only hold a certain number of toys. But what if you have more toys than there are compartments?

Well, that's kind of like computer memory. Sometimes you have more data (toys) than there is space in the memory (compartments). But we don't want to throw away any important data!

That's where bank switching comes in. It's like having a magical toy box with extra compartments that we can switch in and out as needed.

In computer memory, we have different "banks" where we can store data. These banks are like separate compartments in our toy box. When we need to store more data than fits in one bank, we can "switch" to another bank and store the overflow data there.

The computer keeps track of which bank it's currently using and can quickly switch between them when needed. It's kind of like flipping through different pages in a book.

So that's how bank switching works! It helps us store all our important computer data without running out of memory space like we might run out of toy box compartments.
